Kort sagt

Cutaneous lymphoma is an uncommon but serious skin cancer in dogs and cats where abnormal white blood cells accumulate in the skin, causing persistent redness, scaling, hair loss, or lumps that can easily be mistaken for chronic allergies.

A golden retriever with visible hair loss and red, flaky skin on its side.
Cutaneous lymphoma can cause widespread hair loss, redness, and scaling that mimics severe allergies.

TL;DR. Usædvanlig men alvorlig hudkræft: unormale lymfocytter i huden med rødme, skæl, hårtab eller knuder; ofte forvekslet med allergi.

Udbredt hårtab, rødme og skæl kan ligne allergi.

Hvad er det?

Maligne lymfocytter i huden. Epiteliotróp (ofte T-celler, epidermis/mund) vs ikke-epiteliotróp (B/T, dermale/subkutane knuder).

"Nonepitheliotropic lymphoma is a malignant neoplasm that may arise from B or T lymphocytes. It is uncommon in dogs and cats, with highest incidence in older animals. Usually, nonepitheliotropic lymphoma appears as multiple, firm,"

Årsager og risikofaktorer

Årsag uklar. Alder øger risiko. Hunderacer: Boxers, Scottish Terriers, Golden Retrievers, Rottweilers.

Tegn

  • Almindelige: kløe, skæl, plaques/knuder, erytem, alopeci
  • Lejlighedsvis: trædepudehyperkeratose, orale sår, mukokutan depigmentering, lymfadenomegali

A cat's muzzle showing loss of pigment and small ulcerations around the lips.
Mukokutan depigmentering og sår mulige.

Diagnostik

FNA begrænset; biopsi/histopatologi guldstandard. Staging: blod, ultralyd, thoraxrøntgen, lymfeknude-FNA.

"Distinguishing these requires a biopsy sample to assess the tissue distribution of lymphocytes in relation to the epidermis, and this cannot be done with cytological samples."

Behandling

Systemisk: COP Chemotherapy Protocol. Støtte: antibiotika/antimykotika, medicinske bade, analgesi.

Prognose

Langsomt progressiv, helbredelse sjælden. Epiteliotróp ofte langsommere; ikke-epiteliotróp ofte mere aggressiv/systemisk tidligere.

Forebyggelse

Ingen sikker forebyggelse. Tidlig biopsi ved refraktær dermatose.

Hvornår ringe til dyrlæge

Akut: kollaps; vedvarende opkast/diarré; spændt bug; åndenød.

For bestemte racer

Boxer, Scottish Terrier, Golden Retriever, Rottweiler: udred tidligt kroniske hudforandringer og knuder, ikke kun som allergi.
